About the Stock Program<\/h6>\n\t\t\t\t\t

What is the Stock Program?<\/h2>\n\t\t
\n \t\t\t

The stock program<\/strong> is an overview of grades we can supply, with the material number and corresponding ASTM, AISI, or DIN designation for each grade. The program ranges from unalloyed and alloy steel<\/strong> such as 42CrMo4 and 34CrNiMo6 to martensitic, austenitic, and duplex stainless steel, heat-resistant and creep-resistant grades, and precipitation-hardening steel like 17-4PH.<\/p>\n\t\t\t\t\t

The inclusion of a grade in the stock program does not mean that every diameter is immediately available. However, certain grades and diameters are sometimes quickly available from stock<\/strong>, either as bar stock or as raw material for a forging. This can shorten delivery times, for example, for an emergency repair or a maintenance shutdown. We check current availability per inquiry.<\/p>\n\t\t\t\t\t

The table is intended for quick identification. Drawings often list different names for the same material: 1.4462 and F51 for duplex, 1.4501 and F55 for super duplex, 1.6582 and 34CrNiMo6 for the same heat-treatable steel. By listing both designations side-by-side, you can quickly find the grade your specification refers to.<\/p>\n\t\t\n<\/div>\n

From inquiry to delivery<\/h2>\n\t\t
\n
\n \t\t\t

Inquiry & Specification<\/h3>\n\t\t\t\t\t

Provide the material number or ASTM designation, diameter, length, and quantity. We will first check if that combination is available from stock, and if not, which production route is fastest.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Custom Produced<\/h3>\n\t\t\t\t\t

If the size is not in stock, the material will be custom rolled or forged. In-stock material proceeds directly to sawing or pre-machining.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Quality Control & Delivery<\/h3>\n\t\t\t\t\t

Each piece is checked for quality and dimensions and linked to its heat number. We then deliver it in your chosen finish, along with the corresponding documentation.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n\n<\/div>\n

Quality<\/h6>\n\t\t\t\t\t

Certification and Quality Assurance<\/h2>\n\t\t\t\t\t

Fast delivery with us does not mean less control. Material from the stock program also complies with the standard you specify, such as EN, ASTM, ASME, or DIN, and can be supplied according to PED. The material is produced under ISO 9001. You can read how we inspect and document on the quality assurance<\/a> page.<\/p>\n\t\t

Frequently Asked Questions about the Stock Program<\/h2>\n\t\t
\n
\n \n \n \t\t\t

How quickly can material from the stock program be delivered?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

That depends on the combination of grade, diameter, and length<\/strong>. Certain grades and diameters can sometimes be delivered from stock within a short time. If the requested size is not available, the material will be forged or rolled; a pre-machined version can sometimes be ready within 6 working weeks. We check availability immediately and state the delivery date in the quotation.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

\n \n \n \t\t\t

My grade is not on the list. Can you still supply it?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

Yes, in most cases: the list is a selection<\/strong> and not a limit to what is possible. We supply almost all grades, especially in single pieces and small series. Please include your specification with the material number or standard. We will then let you know if the material is from stock or will be custom-made, and what that means for the delivery time.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

\n \n \n \t\t\t

Which heat-treatable and case-hardening steels are in the stock program?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

The program includes heat-treatable steels<\/strong> such as 25CrMo4, 34CrMo4, 42CrMo4<\/a>, 34CrNiMo6<\/a>, and 30CrNiMo8<\/a>. For parts with a hard surface and a tough core, case-hardening steels are included, such as 16MnCr5, 20MnCr5, and 17CrNiMo6, plus the nitriding steel 34CrAlNi7. Which grade is suitable depends on the cross-section and desired hardness; we are happy to advise you on this.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

What do conditions A, H1025, H1075, and H1150 mean for 17-4PH?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

The condition describes the heat treatment<\/strong> of 17-4PH. Condition A is solution-annealed and not intended as a final state. For H-conditions, the material is then aged; the number indicates the aging temperature in degrees Fahrenheit. The higher the number, the lower the hardness and the higher the toughness. Double aged, such as H1150D, means two aging treatments for a stable, tough structure.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

\n \n \n \t\t\t

What is the difference between 15-5PH and 17-4PH?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

15-5PH<\/strong> (1.4545, UNS S15500) is a variant of 17-4PH with less chromium and a more tightly controlled composition, resulting in virtually no delta ferrite in the structure. This provides better toughness, especially transverse to the grain direction and in larger diameters. Magnetic testing is also more reliable, as delta ferrite in 17-4PH can give false indications. Both are aged according to the same H-conditions.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

What is 1.4903 (F91)?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

1.4903<\/strong> (X10CrMoVNb9-1) is the European material number for the grade known as ASTM F91, for example, for forgings according to A182 or A336. It is a creep-resistant martensitic steel with approximately 9% chromium and 1% molybdenum, supplemented with vanadium and niobium. It is used in power plants, where it maintains good creep strength above 500 \u00b0C. Re-tempering is required after welding.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

\n \n \n \t\t\t

Why do some material numbers have the same AISI designation?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

AISI designations are broader than European material numbers. For example, 1.4021, 1.4028, and 1.4034 all fall under AISI 420<\/strong>, but they differ in carbon content and thus in achievable hardness. Also, 1.4404 and 1.4435 are both 316L, with 1.4435 containing more molybdenum. Therefore, state the material number if your application requires a specific composition.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

\n \n \n \t\t\t

Why are A105 and A350 LF2 in the stock program?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

A105 and A350 LF2 are the standard grades for forged flanges and fittings<\/strong> in carbon steel. A105 is intended for ambient and elevated temperatures. A350 LF2 is for low temperatures and is mandatory impact tested, at -46 \u00b0C for Class 1. You can read more about both grades, their composition, and applications on our pages about A105N<\/a> and A350 LF2<\/a>.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

\n \n \n \t\t\t

Can stock material also be supplied machined?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

Yes. We supply material from the stock program rough, pre-machined, or fully machined to drawing<\/strong>. This combines a short lead time for the raw material with custom finishing. For larger or unusual shapes, we prefer a custom forging, so you don't have to machine off unnecessarily large amounts of material.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

\n \n \n \t\t\t

Do I also receive a full certificate with stock material?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

Yes, even stock material<\/strong> comes with an EN 10204 certificate traceable to the original heat. Depending on your requirements and available documentation, this will be a 3.1 or 3.2 certificate. If you require additional tests on the supplied piece itself, such as ultrasonic inspection, hardness measurement, or PMI, this will be done before the material is shipped.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n\n<\/div>\n
